Google on Wednesday unveiled a redesigned version of its Pixel smartphone, part of a refreshed line of devices as part of the tech giant’s efforts to boost its presence against hardware rivals.

The new Pixel 2 and larger Pixel 2 XL are the first Google-made devices since Google announced the acquisition of key segments of Taiwan-based electronics group HTC.

The smartphones will be available for order as of Wednesday in six countries starting at $649 for Pixel 2, and $849 for Pixel 2 XL.

Google said the new aluminum-body smartphones as well as its newly unveiled connected speakers and laptop computer all aim to infuse artificial intelligence to make the devices more user-friendly.

Google vice president Rick Osterloh said Google’s new devices are designed to better integrate hardware and software with artificial intelligence.

“They’re simple to use and they anticipate your needs,” Osterloh told the product launch event in San Francisco.

“You interact with your devices naturally with your voice or by touching them.”

Google, by bringing in a team of engineers from HTC, aims to emulate the success of Apple iPhones by controlling the hardware as well as the software used in the premium-priced handsets.

Google also unveiled a slimmed down version of its digital assistant connected speaker starting at $49 in the United States, stepping up its challenge to market leader Amazon.

The new Google Home Mini is available for pre-order in the seven countries where the device is offered, and will go on sale in stores October 19, the company said.

The new speaker, which responds to voice commands using artificial intelligence, is less than half the price of Google’s first generation speaker and makes this “more accessible to more people,” said Google hardware designer Isabelle Olsson.
